Superconducting wire

Abstract

A superconducting wire includes a superconducting layer. A material for constituting the superconducting layer is an oxide superconductor. In X-ray diffraction using a two-dimensional detector, a peak corresponding to a (200) plane of the oxide superconductor is defined as a first peak, a peak corresponding to a (006) plane of the oxide superconductor is defined as a second peak, and a peak corresponding to a (103) plane or a (013) plane of the oxide superconductor is defined as a third peak. A value obtained by dividing an intensity of the second peak by a sum of an intensity of the first peak, the intensity of the second peak, and an intensity of the third peak is more than or equal to 0.75.
